' To all whom it may concern:

FRANK L. DYE, OF SPRINGFIELD, ILLINOIS.

SLEET CTJ'TTEB AND SCRAPER.

Be it known that. I, FRANK L. DYE, a citizen of the United States,residingat Sprmgfield, in the county of Sangamon and State of.

Illinois, have invented a certain new and useful Sleet Cutter andScraper, of which the following is such a full, clear, and exactdescription as will enable others skilled in the art to which itappertains to make and use my said invention.

This invention relates to sleet cutters and scrapers for cutting thesleet-on trolle wires of electric lines and removing it there om inadvance of the trolley wheels running on said wires. 1 I

The purposes of this invention are to pro.- vide a cutter Wheel and ascraper mounted on an oscillative frame so that said wheel and scraperwill be self-adjusting on the wire to provide means for fixing thecutter and scraper'frame in different positions; to pro- .vide means sothat the cutter and scraper "device may be run in electrical connectionwith the trolley or may be insulated there from; to provide aspring-holding device and means for adjusting the tension thereof tohold the cutter wheel and scraper in contact with the trolley wirewithout exerting undue pressure thereon; to provide guards to pre-. ventthe mechanism from catching on stay wires, in case the trolley isdisplaced; to provide means connecting the cutter and scraper frame withthe trolley ole so that the'parts may be easily detachecf and replacedin case of breakage; and to provide a swivel connection of the cutterand scraper frame with the trolley pole, so that the cutter wheel andscraper will not run off the wire when going around curves;

With these ends in view, my invention consists in the novel features ofconstruction and'combinations of parts shown in the annexed drawings towhich reference is hereby made, and hereinafter articularly described,and finally recited in the claims.

Referring to the drawings, Figures 1 and 2 are respectively a sideelevation and top plan of the com lete device. Fig. 3 is an enlargedartial, longitudinal section on the line X of Fig. 1, and Fig. 4 is anenla. ed partial longitudinal section on theline Y of Fig. 2.

designate 'like -parts in the several views. T e trolley pole 1, theharp 2 andthe trol- Similar reference numerals and characters Iey wheel3 are all of the usual well known construction. The swivel blockconsists of two semi-tubular flanged members 4 and 4 surrounding thetrolley pole 1 and secured together by screws 4 The member 4 has a stud4- on which the swivel frame turns. The swivel frame 5 has upwardlyextending forked members 5 accommodating the socket block 6. A bolt 5extends through the forked members 5 and the block 6 and the block turnson the bolt. The block 6 has a longitudinal socket in which a pole 7 ofinsulating material, preferably wood, fits. The

frame 5 has an o ening 5 accommodating 'a longitudinally shding block 5A screw 5 extends through the end of the frame 5 and acts on the block 5to move the block lengthwise of the opening in the frame.

A spring 8 rests on to of the frame 5 and has an upwardly curve member 8shaped to fit around the under side of the pole 7; members 8 extendingdownwardly into the openin 5' and acted against by the blocks 5"; ancoiled members 8, one on each side of the block 6, so situated that theblock may turn downward between the coiled members.

By turning the screw 5 to the right, the i block 5 may be caused topress against the downwardly extending sprmg members 'to increase thetension of the sprin and reverse" turning of the screw will re ax t etension of the s ring.

The cutte rand scraper frame 9 has a vertical o ning 9 accommodating thescraper 10 an has forked members 9 between whlch the cutter wheel 12turns. A screw '9? ex tending through the end of the frame 9 bearsagainst the double scraper 10 and secures it in any desired position inthe o ening 9.. The frame 9 fits between the for fred members 13 of theharp 13. A bolt 13* extends through the harp members 13 and the'block' 9andpivotally connects the frame 9 with the harp 13. A set screw 13extends through one member 13 'and the inner end of the screw bearsagainst the frame 9 to hold.

ceptionally har service is required the frame swivel block detachablvconnected with said 9 may be adjusted so that both the wheel 12 and thescraper 111 will bear firmly against the under side of the trolley wireand the frame 9 may then be secured by tightening the set screws 13 andthe spring 8 may be caused to exercise the desired increased pressure bytightening the screw 5 to increase the tension of the spring. The harp13 has an integral semi-tubular flanged member 13 fitting around theunder side of the pole 7. A semi-tubular flanged member 13 is connectedwith the member 13 d by a hinge 13". Bolts 13 connect the members 13 and13 so that when the pole 7 is in place between the members and the nutson the bolts are tightened, the pole will be firmly held between themembers.

In case of breakage of the parts the bolts 13' ma be loosened so thatthe iarts may be easiy separated and the bro ken parts replaced. 4

An approximately U-shaped guard 14 has downwardly extending members 14which fit in sockets 13, one on each side of the member 13*.

A collar 15 is suitably secured on the trol ley pole 1 and a curvedguard 15 is secured on the collar 15 and extends upwardly to the upperends of the forked members 5. In case of dis laccment of the cutter 12and scraper 1t) and tpe consequent sudden lifting of the ole 7 am;connected parts, the guards 14 an 15 prevent the staywires connectedwith the trolley wire from catching under the wheel 12 or against thelower end of the swivel block or the swivel frame; and by this meansinjury either to the stay wires or the cutter and scraper mechanism isavoided.

Ordinarily it is preferable that the cutter I and scraper frame shallhave an insulated connection with the trolley pole in order that theaction of the cutter wheel :12 and the scraper 10 may be purelymechanical and also in order to prevent the burning of the cutter wheeland scraper, which might occur if the cutter wheel and scra er framewere electrically connected with t 1e trolley pole. There are howeverconditions under which an electrical connection may be desirable. I makethis connection by means of a wire 16 having one end connected with theswivel block 4 and the other end' connected with the frame 9.

A rope 17 connected with a suitable rctriever (not shown) is connectedwith the trolley harp 2 and the frame 9 so that the trolley harp and theframe 0 may be simultaneously moved in placing the wheels 3 and 12 onthe wire or in removing them therefrmn.
